Looks like Love Island contestant Jess’s suggestion that she didn’t mind if Dom strayed was more for herself, as source claims Jess went behind Dom’s back and slept with Mike on her first night out of the villa.

Jess left the island in tears on Wednesday, along with Mike, and as she said goodbye to her beau Dom, she revealed she would be hopeful that he remained faithful.

‘Jess and Mike fancied the pants off each other from the minute they met,’ the source added.

Speaking to The Sun, they said: ‘They came out of the villa and immediately went back to the hotel where they were both booked to stay, they had separate rooms but couldn’t keep their hands off each other, the sexual chemistry between them is incredible and they couldn’t deny their attraction to each other, one thing led to another and they spent the night in bed together.’

How will Dom feel?

Earlier on Thursday Jess shared a picture of her and Mike leaving the island, writing: ‘Hometime for @mike_thala and I 💔 So sad to leave the island but glad to be home. Thanks so much for all the love and support.’

The news may come as no surprise to fans of Mike’s though, as he previously admitted Jess was his number one choice.

The 24-year-old footballer admitted he fancied the glamour model and glad they left together: ‘The ones I fancied the most, in this order, were Jess, Olivia and Amber.

‘But Jess was in pretty deep with Dom by the time I got there. But I’m blunt, so I’m going to say this: if Dom really had fallen for Jess, he would have followed her out when she was voted off with me, if he was going to wait for her, he’d have left last night too, or today.

‘I’m out with her now and so it’s good to be able to chill with her. We can enjoy our last few days in the sun. Get a bit friendly.’
